This is very similar to the development I've experienced, thank you for sharing the process itself. Our brains naturally chunk information, so the use of schemas to understand abstract concepts I think is completely intuitive. As you pointed out though sometimes a schema can turn out to be an over-simplification which falsely indicates a topic is less complex than it truly is. It's interesting to look over all of the cognitive traps we're vulnerable to which we could never escape if we didn't admit to ourselves we could fall into them.
